Requiem of Death

Exile any number of creature cards from your
graveyard. For each card exiled this way, choose a
creature in play that has not been chosen before.
Put a Deathtouch and a Decayed counter on that
creature.
Recover — Discard a creature card. (When a
creature is put into your graveyard from play, you
may discard a creature card. If you do, return this
card from your graveyard to your hand. Otherwise,
exile this card.)
